ISX Central shows up as a DCAL device on another ISXC when private LANs are shared.

Issue:

ISX Central shows up as a DCAL device on another ISXC when private LANs are shared.

Product Line:

infraStruxure Central / Struxureware Data Center Expert.

Environment:

Potentially any version

Cause:

On rare occasions, some customers may connect the private side of one ISX Central to the private side of a second ISX Central in order to monitor the devices in a redundant type of configuration. The server that has the DHCP server turned on will discover the ISXC server with DHCP turned off as a DCAL device. This is because DCAL, which is an APC specific protocol used in some older power distribution units, can only be discovered on the private ISXC network. Because the one server sees the other trying to communicate using this protocol, it believes it to be a DCAL device.

Resolution:

When configuring 2 servers this way, you must turn off the DHCP server on one of the two servers. This does not cause any adverse communications effects to other devices however the ISXC will continue to report incorrectly.
